To all chom it may concern:

Be it known that 1, WILLIAM NEWTON THonN'roN, a citizen of the UnitedStates, re-

' sidin at Cedar Hill, in the county of Dallas make'and use the same.

and tate of Texas, have invented certain new and useful Improvements inCultivator Attachments; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to My invention relatesto an improvement in cultivator attachments and the object of theinvention is the provision of a device for regulating or varying thewidth oithe low beams so that the low may be made a aptable fordifferent widths of rows or for throwing the dirt close to or away fromthe cultiva'ted article.

"end 8 of t bar 11 .a ter leaving wardly and A further object of theinvention is an improved form of crossed arm support corninedwith asegmental rack.

'-With the foregoing and other objects in view, the invention consistsof certain novelfeatures of construction, combination and arrangement ofparts, as will be more fully descri ed and particularly pointed out inthe ap ended claim.

' 1 n the drawings, Figure 1 is a perspective view of the deviceattached toa pair of plow beams; Fig. '2. is a central horizontalsection taken through the operatinglever pivot.

Referring more especially to the drawings,

1 and 2 represent the cultivator plow beams to which is attached b meansof the clevises 3 the crossed arms or evers 4. These levers are providedat'their'lower ends with right angular hook ends 5 which engage the eyes6 formed the upper ends of the clevis. will thus be seen that whileinsecure attachment is made for any lateral .or shaking movement of thearms, that they may be easily and quickly detached and applied withoutthe use of tools. The arms 4 are pivoted together by therethrou h andthrough the bifurcated i6 lever supporting structure 9.

This lever supporting structure extends u rearwardly on the arc of t iscircle from the bifurcated end tothe 'junction of the operating leverspivotal point 10, to be hereinafter described, in the form of two soarated bars 11 and 12. The mema bolt 7 which passes,

the pivotal point 10 is- Speification of Letters Patent. .ii ncauo 'meam e, 1908. Serial no. sea-Isa.

bent downwardly and rearwardly to suppkort Patented June 8, 19508.

the lower end of the segmental rack 13f he u per end of the segmentalrack is supported directly by the vertical member 14 of the member 12and the operating lever-15 is pivoted between the two to lie alon sideof the segmental rack or by the pivotal The forward end of the leversupporting structure 9 'is provided with an eye 16 to which a link 17 issecured having a clevis or clip 18 in its outer end which is aperturedto engage a suitable bolt or pin formed on the rear end of thecultivator tongue or which may be attached to any" other suitableportion of the frame to hold the stincture in upright position. I

The up er ends of the levers 4 are connected to inks T-shaped couplin 20having bifurcated ends to receive the lin s 19-and a de 21 which isconnected to the lin 22 exten ing downwardly therefrom into pivotal enageinent with the outer end of the operating ever 15.

The operating lever 15 is provided with a suitable s ring-pressedlocking dog 23 which is control ed by a handle 24 pivoted to the lever15, and ositioned approximately arallel to a handle 25 formed on thelever. he handle 25 on mately right angles thereto so as to be in Bolt10.

ending arm the lever is formed at approxi 19which extend inwardly to asubstantially vertical position when the levers t are contracted.From-the foregoing description taken in connection with the accompanyingdrawlugs, the construction and operation of the invention will bereadily understood without re uiring a more extended explanation.

arious changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the rinciple orsacrificing any of the advanta es of the invention, asdefined in theappenc ed claim.
